The Emyn Muil lies between the eastern part of Rohan and the relatively empty lands that contained the Dead Marshes and the Nindalf (Wetwang). It was approximately seventy-five miles from east to west and some one-hundred miles from north to south.
The Emyn Muil had once marked the northern borders of the Kingdom of Gondor at its height.
Significance in the Lord of the RingsEdit
At the beginning of The Two Towers, Frodo and Sam, attempting to reach the Black Gate of Mordor, are lost in the eastern Emyn Muil for days until Gollum finds them. After a great deal of persuasion, he agrees to show them the way, leading them south into the Dead Marshes.
